[SciPy-User] sqrtm is too slow for matrices of size 1000

I am implementing spectral clustering for my course work and am using the 
sqrtm function to find the square root of a matrix . But its far too slow, 
my matrix is of size (1258,1258). Any suggestions on how I can speed things 
up or some other function that scipy supports which can be used. 

I am implementing the algorithm as described here:

Finding the square root of D^(-1) is way too slow for D^-1 of size
